CONCRETE-AND-METAL CONSTRUCTION.

Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed June 13,1904. Serial No. 212,296.

To all whom it may concern:

Be it known that I, ALBERT L. JOHNSON, a citizen of the United States, and a resident of the city of St. Louis, and State of Missouri, have invented anew and useful Improvement in Concrete-and-Metal Construction, of which the following is a specification.

My invention relates to constructions of concrete reinforced with metal, and has for its principal objects to adapt such constructions for use for retaining-walls, dams, and the like.

My invention consists in the arrangements and combinations of parts, substantially as hereinafter described and claimed.

In the accompanying drawings, which form part of this specificaton, and wherein like symbols refer to like parts wherever they occur, Figure l'is a vertical sectional elevation of a structure embodyin my invention. Fig. 2 is a front elevation of t 1e modification of said structure seen in Fig. 3, and Fig. 3 is a vertical sectional elevation of said modified structure.

The footing comprises a thick slab or foundation of concrete having metal reinforcing bars or rods embedded horizontally therein. Some of these reinforcing bars or rods 2 are arranged longitudinally near the upper and lower surfaces of the footing, and others, 3, are arranged transversely near the lower surface. Upon the footing, at or near the outer side thereof, is built a face-wall 4, of concrete, having reinforcing bars or rods embedded therein near its outer surface. Some of the bars 5 in the facewall are arranged horizontally, and others, 6, are arranged transversely, the transverse bars preferably being extended down into and embedded in the footing.

-A- series of vertical strengthening-ribs 7 are built'iip on the footing 1 transverse to the faceewall 4. These ribs 7 are of triangular shape, inclinin upwardly from near the rear or inner side of the footing to the upper portion of the vertical wall. These ribs have embedded therein reinforcing bars or rods whose ends are preferably anchored in the footing and in the walls resting on the ribs. This anchoring is conveniently effected by doubling back the ends of the bars or rods to form hooks which engage the horizontal bars' or rods in the footing and in the other Walls, res ectivel n practice the several portions of my construction will be built simultaneously and in one continuous mass of concrete by the use of centering or false work, as is usual in concrete construction, and preferably the reinforcing metal will be corrugated bars of the kind fully shown and described in my'a lication for Letters Patent therefor, Serial lQo. 194,362, filed by me February 19, 1904.

A structure of this general description is herein shown utilized in dam construction, though, obviously, it is also well adapted for retaining-walls. the width of the footing is practically equal to or greater than the face-wall and is generally cemented water-tight to bed-rock.

In the construction shown in Fig. 3 the face-Wall 4 has a considerable inclination and rests upon the footing and upon the triangular ribs or transverse walls 7 on said footing. These transverse walls are preferably reinforced with horizontal bars 2, extending into the face-wall, and with vertical bars 11, whose lower ends extend into the footing, and may have books for engaging the bars therein and whose upper ends extend into the face-wall. This construction is designed to have the water bear against the outer surface of the inclined face-wall; but it is capablev of use with the water entering between the ribs, in which case the reinforcing metal is embedded near the outer surface of the face-wall. In either case the weight of the water contributes to the stability of the dam. In this construction it is unnecessary to fill in the space between the ribs, and consequently it is unnecessary to inclose said space with a wall at the rear of the structure.

The construction shown in Fig. 1 is designed to have the vertical wall 4 used for the face-wall. This vertical wall has the horizontal bars 5 and vertical bars 6 embedded near its rear and horizontal bars 5 and vertical bars 6 embedded near its front surface. The ribs 7 are built upon a footing, as described, and constitute buttresses for the facewall. These ribs are of triangular shape, and the space between them may be filled in withcheap material and inclosed with a rear inclined ends of the ribs. has horizontal bars 9 and bars 10 embedded near its outer surface. The lower ends of these last-mentioned bars extend into the footing, and the upper ends extend to the front wall or to the u permost portion of the construction, which is tied to said front wall by horizontal bars 13.

In some cases where the construction is wall 12, which rests against the, This rear wall upwardly-inclined 5 In the construction shown t liable to be exposed to Water-pressure on each side it is desirable to have two vertical face-walls.v In such cases the transverse ribs are of rectangular rather than triangular forin.

Obviously my invention is applicable to other-uses Where itis desirable to increase the transverse strength of a wall, as in the case of bridge abutments, piers, and the like. Consequently I do not wish to be limited to the exact details of constructionshereinbefore shown. 7

What I claim is 1. A darn comprising a footing, aface-w all thereon, and vertical ribs arranged transversely on said footing and having their ends inclined, and an inclined \vall arising directly from said foo.ing and resiiig against the inclined ends of said ribs, all made of concre'te and reinforced with layers of longitudinally and ti ansvcrsclv arranged metal rods, whereby the face-wall and the inclined wall are anchored to each other and to the footing.

2. A dan'tcoinprising a footing, a face-wall i coucrtne reinforced with metal bars, vertical] thereon, and vertical ribs arranged transversely on said footing and having their ends inclined, and an inclined \vall arising directly from the footing resing against the inclined ends of said ribs and uniting integrally the uppcredge of the face-wall \\'ltlll'l1( footing. all made of concrete reinforced Wit It layers of longitudinally and transversely arranged rods of inet al.

3. A dani comprising a footing, vertical iibs arranged transversely on said footing and having their ends ii tclined, and an inclined \vall arising directly from said footing and resting upon the inclined ends of said ribs, all made of concrete reinforced with metal rods, \vhich anchor the inclined ,tvall to the footing through said ribs.

1 footing resting on the inclined ends of said ribs, said inclined wall having transverse bars whose lower ends are embedded in the looting, and said ribs having vertical rods whose ends extend into the inclined wall and into the footing the width of said footing be- 1 ing subst an. iallv as great as the height of the inclined wall.

5. A concrete (lain comprising a footing of concrete reinforced with metal bars, vertical l'ibs of concrete arranged transversely on said footing, and an inclined wall resting on said footing and against said ribs, said inclined wall having transverse bars embedded therein. and said ribs having horizontal bars extending into said wall and having vertical bars extending into said foo.ing and into said all. said \'.(1"tl(:ll bars having hooks at, their lower end arranged to engage the bars of said footing.

(S. A concrete dain comprising a footing of ribs of concrete arranged transversely on said foo.ing, and aninclined Wall resting onsaid. fooing and against said ribs, said inclined wall having transverse bars embedded therein. and said ribs having horizontal bars extending front end to end thereof and into said wall and said ribs having vertical bars extending into said footing and into said ins clined wall thereby anchoring said walls together through said ribs.
